Blake Shelton knows the way to a woman's heart!
The sexy country singer appears on Monday's "The Ellen DeGeneres" show where he opens up about his new song, "Go Ahead Break My Heart," with girlfriend Gwen Stefani.
According to Shelton, the couple -- who performed their duet live on Sunday's Billboard Music Awards -- first collaborated on the song together before their romance got serious.
"I think the thing about it is, when we wrote the song we never saw it going there," he tells Ellen in a new sneak peek. "I don't know that we ever saw it going anywhere."
"I only started the song to impress her, to be like 'Hey, writin' a song about ya.' So I sent it to her and she wrote the other half of the song and it's like oh, she just one-upped me," he jokes.
Clearly, Blake's strong feelings for Gwen are mutual!
The "Used To Love You" singer couldn't help but post a few photos from their special night in Las Vegas, after sharing the stage at the Billboard Awards.
"@blakeshelton @billboard #goaheadandbreakmyheart #vegas #whoknew?," Gwen posted with a pic of her and Shelton in Sin City.
Stefani also shared a second shot with the "Came Here To Forget" singer, as he's pictured grabbing her legs. "#vegas #GoAheadAndBreakMyHeart @billboard," she captioned the cute candid.
